First, perform the operations inside the parentheses and the exponent: $3^2 = 9$. Then, calculate the numerator: $10 \cdot 7 - 9 = 70 - 9 = 61$. For the denominator, calculate the value inside the parentheses first: $2 \cdot 10 = 20$, then add 9 to get $9 + 20 = 29$. So, the expression simplifies to $\frac{61}{29}$.
